Can pre-screening be required for hepatitis B titer? Post-screening?

The employer cannot require an employee to take a pre-screening or post-vaccination serological test. An employer may, however, decide to make pre-screening available at no cost to the employee.

All medical evaluations and procedures, including the hepatitis B vaccine and vaccination series, are to be provided according to the current recommendations of the U.S. Public Health Service.

According to the current guidelines, employees who have ongoing contact with patients or blood and are at ongoing risk for percutaneous injuries should be tested for anti-HBs one to two months after the completion of the three-dose vaccination series. Non-responders must receive a second three-dose series and be retested after the second series. Non-responders must be medically evaluated.
